It had the soonest virtual impactor of an asteroid larger than 50 meters in diameter with a better than 1:1,000,000 chance of impacting Earth. On 11 March 2023, the line of variations (LOV) showed a 1-in-500,000 chance of impact. It has a short observation arc of 3 days. On 11 March 2023, it was nominally expected to be 2.7 AU e6km unit on from Earth but had an uncertainty region billions of kilometers long. Since it has not been observed since 2005 and has an orbital period of 2.6 0.3 years, it is unknown where on its orbit 2005 ED 224 is. Between 2005 and 2023, it could have orbited the Sun 6.2 to 7.8 times. On 11 March 2030, it has a 1-in-6,300,000 chance of impact but is expected to be 3.5 AU e6km unit from Earth (near the asteroid's farthest distance from the Sun). On 10 March 2064, it has a 1-in-2,600,000 chance of impact but is expected to be 3.2 AU e6km unit from Earth. It was first observed on 13 March 2005 when the asteroid was estimated to be 0.056 +/- 0.006 AU e6km unit in from Earth and had a solar elongation of 137 degrees. +Virtual impactors (past and future) Date Impactprobability(1 in) JPL Horizonsnominal geocentricdistance (AU) NEODySnominal geocentricdistance (AU) MPCnominal geocentricdistance (AU) Find_Orbnominal geocentricdistance (AU) uncertaintyregion(3-sigma)2018-03-11 2.4 million 1.7 AU e6km unit on 1.7 AU e6km unit 1.4 AU e6km unit 1.2 AU e6km unit ± 5 billion km2023-03-11 500 thousand 2.7 AU e6km unit 2.7 AU e6km unit 0.95 AU e6km unit 4.0 AU e6km unit ± 3 billion km The 11 March 2018 virtual impactor did not occur. The line of variation (LOV) for 2018 was billions of kilometers long and wrapped around the asteroid's orbit so that the asteroid could have been numerous different distances from the Earth. The 2023 line of variation (LOV) was also billions of kilometers long and stretched around the asteroid's known orbit.
